MPRQ cannot be used in multi-process applications because of externally attached MPRQ buffers. A callback is registered by a primary process to free MPRQ buffers once they are no longer needed. But this information is shared among all the processes. The virtual address of the mlx5_mprq_buf_free_cb function is different in a secondary process, which leads to a segmentation fault. Document that MPRQ is not supported in a multi-process app, since there is no way to find out if this is the one.
